Additional feature to help you forward

Within the setup overview menu there are features programmed to help you to improve the laptime of the given setup on the used track.

In this menu we describe these features and explain how they are calculated.

Next to that we describe some other features which are implemented in the plot menu's. These features were implemented in LapSim because they helped us when we worked with LapSim ourselves.

Advice about changing your LapSim vehicle setup

If you open the setup overview with a simulation run selected, you will see that the weightbalance, the ARB stiffness and the brake balance values are shown on a pushbutton.

Pushing either of them will cause LapSim to make an estimate in which direction the parameter should be changed to improve laptime.

Estimate for brake temperatures after 10 laps

If you select 'Brakes' in the plot menu, 6 edit boxes will appear where you can edit parameters of your brake system.

With these parameters a simplified brake temperature simulation is done, based on the brake energy generated by the selected simulation runs.

Apart from the brake energy there is the cooling, which is dependent on the speed, brake disc size and relative cooling.

The disk size in combination with what is called 'heat capacity' determine the thermal mass.

What results is a temperature trace. We like to emphasize that you should use the traces for comparisons, without looking to much on the absolute values.

In the example you see the effect of adding 25 [Hp] to engine power on the brake temperatures.

Making 'faulty' on-car data usable

We often see data with an offset on the suspension travel signals. Experience has shown that even when the signals are properly zeroed, a suspensions need to 'set', creating again an offset.

Especially when you are trying to get a good correlation between model and reality, this complicates matters. Makes the recorded data less usable, which can be easily be improved. Therefor we have made this option to add an offset to the suspension travel signals.

If you select the suspension travel in the plot menu and the on-car recorded data is the selected lap, you are able to add an offset to the traces.
